The Web vs. Library Databases – A comparison The Web (Google, Wikipedia, About.com, etc.) Varies at best. Difficult to verify. Cannot limit to professional, scholarly literature. Information on the Web is seldom regulated, which means authority is often in doubt.
Databases (Academic Search, Lexis-Nexis, etc.) Easy to determine. Most databases have scholarly/peer-reviewed filter or contain only scholarly literature. Authority and trustworthiness are virtually guaranteed.
Number of Hits
1000’s, sometimes millions of hits, much of the same information repackaged or duplicated. Duplicates are not filtered out.
Dozens to hundreds of hits (sometimes 1000’s but not 100’s of 1000’s) - a more manageable number, and duplicates can be filtered out.
Relevance
Lack of subject focus can result in numerous irrelevant hits – or “junk” – to wade through. Much Web infomation is opinionated and biased. Unless you are using a subject-specific search engine, expect “everything and the kitchen sink” in the results. Quantity ≠ Quality
Focus by subject (business, art, American history) and/or format (journals, books, book reviews), which often means more relevant information and less time wasted dealing with junk. Information comes from legitimate, qualitycontrolled sources.
Search Features
Varies by search engine, but often limited. Can limit by document type (.doc, .pdf) or language, but limiting by publication date, format (article, book, etc.), scholarly/peer-reviewed and more is unavailable.
Numerous advanced search features determined by database subject focus, e.g., limiting by publication type, date, language, document format, scholarly/peer-reviewed status. The list of features is as long as the number of databases available.
Access to Published Information
Web information often lives and dies on the Web and can come from anyone with Internet access. Seldom is the information coming from legitimate published sources: magazines, academic journals, books, etc. When it is, the user usually has to pay to access it.
Databases deal only with published information; that is information that originally appeared in print: magazine and journal articles, books, etc. They are more stable than the Web. Through the library’s paid access, all of this information is available to you, the user, for free.
Authority
5 Criteria for Evaluating Web Sites (Applicable to Any Media): To determine whether a site’s contents (or any media’s contents – books, newspapers, television, etc.) can be trusted, it is best that that you carefully evaluate the site. See below for questions to ask when determining whether a site (or other media) contains sound information. 1. Audience – To whom is the site directed – children, adults, students; a certain ethnicity, gender or political affiliation? Is it understandable by the layman, or is it highly technical requiring specialized knowledge? 2. Authority – Is the author of the site listed? Can you determine his/her expertise? Is contact information given – phone number, address, e-mail? With what organization is he/she associated? 3. Bias - Does the language, tone, or treatment of its subject give the site a particular slant or bias? Is the site objective? Is it designed to sway opinion? Organizational affiliation can often indicate bias. 4. Currency – Is the site up-to-date with working links? Are dates given for when it was created and last updated? Is the topic current? 5. Scope – Is the site an in-depth study of the topic going several pages deep, or is it a superficial, single-page look at the subject? Are statistics and sources referenced properly cited? Does the site offer unique information not found anywhere else, e.g., print sources? Thanks to the University of Maryland and the University of Dallas for providing the content for this tool.
Peer-Reviewed or Scholarly Journals vs. Magazines: What’s the difference? One of the main reasons researchers turn to databases is to have the ability to search for peer-reviewed articles. The following briefly explains how peer-reviewed articles differ from popular articles. Popular Magazines (Time, People, etc.)
Scholarly/Peer Reviewed Journals (Journal of the American Medical Associaion, etc.)
Intended for a general audience. Intended for an audience with knowledge in the field. Articles written by journalists who may or may not have special training in what they are writing about.
Articles are written by scholars, whose names are listed along with credentials.
Articles do not have footnotes. Articles are footnoted and list sources used. For Profit. Usually not for profit. Not Peer-reviewed. Peer-reviewed.
How do I find peer-reviewed articles and journals? Use a scholarly database rather than a general database (Historical Abstracts vs. Academic Search).
When available, limit to scholarly/peer-reviewed journals when you search your database.
Check in Ulrichsweb (library database) to see if the journal you want is peerreviewed.

I. AUTHORITY AND ACCURACY It is important to find out who is the author and what are the author's qualifications or expertise, in order to determine the credibility and reliability of the information you find on the website. Who is the author of the Web site? What part of the URL (Web address) gave you clues about authorship? Check all that apply:
(.com).a company
(.org) non-profit organization
(.edu) academic institution
(.uk) country sponsored site
(.gov) U.S. Government agency
(www.jamieoliver.com) a personal Web page
(.mil) U.S. military site
Other? Please describe:
(.net) network of computers What are the qualifications of the author or group that created the site?
II. PURPOSE AND CONTENT Determine the purpose of the Web site by looking closely at the content of the information. Some sites provide links to information about our organization or a Mission Statement, detailing the purpose in creating the Web site, while the purpose of others might not be obvious at first. What is the purpose of the Web page or site? Check all that apply: a personal Web page. a company or organization Web site. a forum for educational/public service information. a forum for scholarly/research information. for entertainment. an advertisement or electronic commerce.

When was the Web site last revised, modified or updated?
Is currency important to the type of information available on this Web site?
Is the site well-maintained?
IV. DESIGN, ORGANIZATION AND EASE OF USE Design, organization and ease of use are important considerations. Web sites can provide useful sources of information. However, if they are slow to load or difficult to navigate, search and read, then their contribution and usefulness will be lost. In your opinion, how does the Web site appear overall? Check all that apply:
Well designed and organized.
Poorly designed and organized.
Easy to read and navigate.
